v4.2.3: full recon arsenal (KingOfBugBounty), version bump

RECON_SYS enriched with the concrete bug-bounty recon arsenal and tool pipelines
(subfinder/amass/assetfinder/crt.sh → httpx liveness → gau/waybackurls/katana/
gospider URL harvest → JS analysis & secret regexes → arjun/x8 params → gf vuln
patterns + qsreplace → ffuf/feroxbuster content discovery → naabu ports → dnsx/
nuclei takeovers → cloud bucket grep → targeted nuclei → chained pipeline),
passive-first and scope-respecting. Shared by the black-box run path, so it
applies identically to the CLI, the REPL and the web console.

Version bumped to 4.2.3 across CLI/clap/web/README/TUTORIAL. 423 tests.
